Machinima: "During Nintendo’s Wii U-specific press conference earlier this week, Activision Publishing CEO Eric Hirshberg announced that their upcoming Call of Duty title, Black Ops 2, would be coming to Nintendo’s forthcoming console. Shortly after the announcement was made, we were invited to try it out for ourselves."

People may be disagreeing with your lack of knowledge on the situation... which is kind of stupid. If that is why, they could have just told you...-_-;;
Regardless, don't worry about it. ^_^
Edit: I just checked, it has stereo speakers so it doesn't need the headphones to hear things…
You may be able to google that part of the conference and see if they mention it. I can't imagine they wouldn't support these features...
